I have a simple black and white design which I have as an svg or tiff file (basically it’s a design for a grating to go on front of a telescope), and I’d like to be able to import it to Sketchup, extrude it by a couple of mm, and then prepare it for 3D printing.
Rather than it being simply a texture for a 3d surface, I’d like the blanks in the design to be holes, and the black bits to be solid, hope that makes sense ?
Manually digitizing the raster data by sketching over the image will lead to extrudable vectors.
Vector data of SVGs cannot be imported natively by SU but you can convert them to the DWG/DXF format (= industry standard for 2D CAD data) by using free Inkscape.
